Sip and yak away, cancer expert says

Drinking coffee, talking on your cell phone or having breast implants is unlikely to cause cancer, according to a new risk ranking system done by an Australian cancer specialist.

Doctor Bernard Stewart made lists of cancer risks from proven and likely to unknown or unlikely. He found little cancer risk from coffee, breast implants, deodorants, fluoridated water and dental fillings.

Research shows cell phone use less likely to cause cancer, but the risk of long term use of cell phones was not known. Leadings risks included smoking, alcohol and exposure to sunlight.
